MailMerge.Execute throws null exception on Word doc with unknown merge fields


I have just started using the Aspose.Word version 16.5 to handle word merges. It seems that when I run call Execute(datatable) against a word document with merge fields that don’t exist as columns in that datatable the call throws an exception. I believe the older version just ignores those fields.

Are there options i need to set to prevent this from happening? Thanks for your help.
